Sam/1's FOREARM GUN Howard C.Sarvis, Boulder Creek Station, New Meadows, Idaho Filed Oct. 10, 1955,Ser. N0. 539,470 18 Claims. (Cl. 42-94) This invention relates to gunsof the class adapted for mounting on the forearm and for shooting whenthus mounted.

There are many instances in which armed guards, police officers, armoredcar operators and military personnel are under the necessity of workingwith their hands in the performance of various tasks where-aninstantaneous need may arise for use of a gun. Such instances areparticularly common in warfare, in the case of personnel not primarilyrifle men, such as raiders, vehicle operators, artil lery men, bazookaand mortar men, technical personnel, ofiicers, etc. These classes ofindividuals have many tasks to perform requiring the full use of bothhands, yet they often work sufficiently close to the front to be subjectto enemy surprise and hence require the instant use of a.

personal weapon of defense. In these situations the guns which arecurrently available, including holster weapons, carbines and sub-machineguns, are unsatisfactory because of the delay experienced in mountingand firing them. 1 Accordingly it is the general object of the presentinvention to provide a gun which may be carried on'the forearm and firedinstantaneously while thus carried, without materially hampering the useof the hands and arms of the wearer for other tasks. 1

The advantages of the forearm gun provided by the present invention thusinclude the following:

(1) It can be worn comfortably over long periods of. time withoutcutting off the circulation, irritating the' nerves, or pinching theskin.

(2) It may be mounted upon and demounted fromthe forearm substantiallyinstantaneously.

(3) It is instantaneously and automatically adjustable for use uponforearms of varying lengths and thickness.

(4) It is mountable readily upon a belt worn about the waist when it isnot urgently needed.

(5) It may be fired when mounted on the forearm, on the belt, or whenit-is held in the hands.

(6) When mounted on the forearm it is stable and may be sighted andfired accurately.

(7) It is mounted on the forearm in such a manner that its recoil is notoffensive or a problem.

Generally stated, the forearm gun of this invention comprises a gun bodyof suitable dimensions for mounting on the forearm-means for releasablysecuring the rear terminal portion of the gun body to the forearm andabout the waist when this is desired; for accommodating 1 upper arm, andmeans for releasably securing the forward terminal portion of the gunbody to the hand. Means also are provided for mounting the gun on a beltworn guns of various lengths on the mounting means on the arm and on thebelt; and for triggering the gun positively The gun The generalcharacter of the forearm gun described herein and of the mount employedfor it is apparent from Figs. 1, 2 and 3. The gun may be of any typehaving dimensions suitable for mounting on the forearm. Thus it may bespecially designed, or it may comprise a modified or unmodified standardgun type such as a .45 caliber hand gun, or particularly, a modi: fiedU.S. Army 'Ml or M-2 carbine.

A carbine type gun is shown'in the illustration. As shown, the stockhas' been removed and the barrel shortened. Otherwise it includes theusual mechanical elements associated with guns of this class includingbolt, slide and cocking hook assembly 22, cartridge clip 24, trigger 25,and muzzle 26.

' The gun mounting assembly The gun mounting and firing elements of theherein described assembly may be attached directly to the gun body,particularly where the latter is designed and dimensioned especially foruse as a forearm gun. However, where a standard carbine or other gun isadapted for such use, it may be mounted in a casing indicated generallyat to shield the mechanism and hot barrel. This casing conformsgenerally to the contour of the gun and is provided with suitableopenings for loading and firing the gun.

Means are provided for mounting the gun or the gun casing, as the casemay be, on the forearm of the user The means employed for this purposecomprise broadly a. harnessfor mounting the rear terminal portion of thegun on the forearm and upper arm, and a grip for mounting the muzzleportion of the gun on the hand. A rear sight 32 then is mounted in anappropriate po' sition on the upper surface of the casing for use inconjunction with front sight 33. Also, a perforated bracket 34 extendslaterally from the side of the casing for mounting the gun on the beltas will be explained hereinafter.

For mounting the rear terminal portion of the gun on the forearm thereis provided, on the upper inner side edge of the casing, a hook 36having in its upper under surface a pair of spaced apart projections ordogs 38, 40 (Figs. 15-17). This hook cooperates with a clip indicatedgenerally at 42 and stationed on the lower insfde, edge of the casingpreferably in substantial vertical alignment with hook 36.

Although clip 42 may be variously constructed, in the illustrated formit comprises a shank portion 44 and a clip or latch portion 46. Theshank portIon is pivotally attached to an extension of casing 30 bymeans of pin 48. A resilient means such as spring 50 is provided formaintaining the clip normally in its advanced, operative position.

Hook 36 and clip 42 are designed and dimensioned for attachment to aharness assembly by means of which the rear terminal portion of the gunis mounted on and supported by the forearm and upper arm of the user.This assembly includes a first plate 52 having along its upper edge aplurality of serrations 54, the spacing of which corresponds to thespacing between projections 38, 40 on clip 36. The length of theserrated surface of the plate is sufiicient to enable mounting of gunbodies of varying length on forearms of varying length.

The forward portion of plate 52 carries a laterally extending secondplate 56. This plate preferably is arcuate in contour to conform to thecontour of the upper forearm surface which it engages. It may be paddedwith sheepskin or other suitable material for comfort and safety. It isconnectible to an adjustable strap 58, the lower end of which is affixedto the lower edge portion of plate 52, and the upper end of which isprovided with a snap fastener 60 for releasable attachment to plate 56.

Plate 52 is articulated with a third plate 62 by means of a pin 64 whichpenetrates overlapped extensions of the two plates. It is to be notedparticularly that plates 52 and 62 are proportioned'and positioned insuch a manner that pin 64 is aligned with the elbow joint. Accordinglyas the forearm is raised and lowered in a normal manner, plate52'follows this motion without impeding or hindering it.

Plate 62 is generally arcuatc in contour to conform to the upper surfaceof the upper arm. A cooperating fourth plate 66 is arcuate to conform tothe contour of the lower surface of the upper arm. The two plates areinterconnected by suitable means such as adjustable straps 68, 70interconnecting one pair of opposite side edges of the two plates, andadjustable straps 72, 74- interconnecting the other pair of oppositeside edges of the plates. Suitable means such as snap fasteners 76, 78may be provided for releasably attaching the ends of straps '72, 74 toone or the other of the plates, preferably plate 62. Thus the supportingharness including plate 52 may be mounted on the arm easily and rapidlyby the simple expedient of closing snap fasteners 60, 76 and 78.

As indicated above, the forward or muzzle portion of the gun issupported by the hand of the user. For this purpose, there is providedon the forward portion of the inner side of casing 30, or of the gunbody if a. casing is. not employed, a grip assembly indicated generallyat 80.

The construction of a suitable form of such an assembly is illustratedparticularly in Figs. 5 and 6. Thus it may comprise a rigid,yoke-shaped, hollow, horizontal cross piece 82, one end of which isattached to the upper edge of the forward portion of casing 39. Theouter edge of cross piece 82 connects with a vertical bracket 84 whichalso is hollow. It carries a housing 86 which preferably issubstantially square in cross section and which contains the triggeractuating mechanism, as will be explained more fully below.

Attached to the lower end of bracket 84, or of housing 86, is a flexiblelink member indicated generally by the numeral 88 and includingpreferably a flexible metal strap. 90 (Fig. 7) contained in a flexibletube 92.

The lower end of strap 90 is attached through a pin 94 to the lowerouter end of a rigid cross piece 96. The upper end of this cross pieceis attached to or integral with the lower inside edge of the forwardportion of casing 30 or to the lower front portion of the gun body asthe case may be.

An adjustable strap 97 interconnects the central portion of upper crosspiece 82 and the lower portion of flexible connector 88. Thus, as isparticularly apparent in Figs. 1 and 5, strap 97 forms with bracket 84and connector 88 a loop through which the fingers and the for- Wardportion of the palm of the hand may be inserted. Since this opening isadjustable, the mount is adaptable for use by persons having differentsized hands, and also by persons wearing heavy gloves in cold weather.

From the foregoing it will be evident that the herein described forearmgun may readily be mounted on the arm. This is accomplished simply byplacing the fingers of the hand through the opening formed by strap 97,bracket 84 and connector 88 until a comfortable operating position isattained. The rearward portion of the gun then is placed adjacent plate52 on the arm harness. Thereupon book 36 may be slipped over serratededge 54 of the plate, where it automatically will engage appropriateones of the serrations. This makes possible automatic and immediateadjustment of the assembly for use by personshaving forearms ofdifferent lengths.

Clip 42 then may be snapped under the lower edge of plate 52. Thiscompletes the mounting operation in circumstances wherein it is desiredto have the gun in readiness for immediate use.

Alternate mounting means are provided, however, for mounting the gun atthe waist of the wearer where the need for use is not so urgent. Asuitable belt mounting means for this purpose is illustrated in Figs. 1,2, 15 and 16.

It includes an adjustable belt 98 to the front of which is attached anelongated plate 100. Attached to plate 100, or formed integrallytherewith, is a second plate 102 having a serrated edge 104. Thedimensions of these serrations are identical with those of theserrations 54 on plate 52. Hence they are adapted for the reception ofprojections 38, 40 on hook 36 of the gun casing.

Also provided on plate 100 is a belt hook or dog 106. This member isdimensioned for-reception in the opening in bracket 34 on the gun casingreferred to hereinabove. As a consequence, the front portion of the gunmay be rapidly mounted on the belt by inserting belt hook 106 in theopening in bracket 34. The rear portion of the gun then may be connectedto the plate by slipping book 36 over the serrations 104, on the topedge of plate 102, and snapping clip 42 over the bottom'edge thereof.

When the gun is thus mounted at the waist, it may be carried comfortablyand securely for long periods. However, it is ready for immediateattachment to the forearm, or may even be aimed With an appropriateswinging motion of the body and fired from the waist, using the lefthand to pull the trigger.

The triggering mechanism' As is apparent from a consideration of Figs.6-14, the gun trigger preferably is actuated by means of the rightthumb. This makes possible firing the gun even though heavy mittens orgloves are being worn. It also minimizes fiinching of the marksman whenthe gun is fired.

Accordingly the trigger actuating mechanism is mounted in part inhousing 86 which, as has been indicated above, is connected to bracket84 of grip 80. As will be seen from Figs. '1 and 3, this places thetrigger actuator directly adjacent the thumb when the fingers of thehand are inserted through the grip.

In the illustrated form, the trigger actuator comprises a button 110having thereon a laterally extending wing 112. The latter element servesas a safety for the gun.

For this purpose the upper surface ofv housing 86 is formed with a cutaway portion 114 and a communicating vertical slot 116.

When button 110 is in the position of Fig. 7, wing 112 abuts against theedge of cut away portion 114 of housing 86. Accordingly the button cannot be depressed and the gun is in locked or safety position. However,when button 110 is rotated through 90 and assumes the position of Fig.8, wing 112 registers with slot 116. The button then can be depressed,and the gun will be in firing position.

To make the rotary movement of button 110 between its safety and firingpositions more positive, and to insure that it will not stop at anintermediate position, positioning means illustrated particularlyin'Fig. 9 are provided. For this purpose the shank of button 110contains a central transverse opening 120. A compression spring 122 isseated in this opening. Balls 124, 126 are seated in the terminalportions of the opening in resilient contact with the ends of thespring.

Since housing 86 is square in cross section, it will be evident thatwhen wing 112 is in the safety position of Fig. 7, balls 124, 126 willnest partly in opening 120 through the button and partly in the cornersof the bolls.

122 will force them out into the other opposed pair of corners of thehousing. This positions the safety very accurately in on and offpositions.

Button is connected to a plunger 130. Unlike the button, which iscircular in cross section, plunger is square in cross section and is insliding engagement with the inner side walls of housing 86. Itisreleasably connected to the lower end of the button by interengaging aflange 132 on the latter with a correspondingly dimensioned slot in thehead of the plunger. a

Vertical sliding movement of plunger 130 is restricted by means of aspring pressed stop 134. This stop is formed with a projecting head 136and is mounted in a recess 138 in a side wall .of the plunger. The stopis backed up by a compression spring 140 which normally urges itoutwardly with head 136 extending through a slot 141 of restricteddimensions in housing 86. As a result, button 110 and plunger 130 can bemoved vertically to an extent determined by the dimensions of slot 141.Also, if it is desired to remove the plunger and button from thehousing, the head of the stop may be depressed until it clears the innerside wall of the housing. Thereafter the plunger and button may beeasily extracted.

The lower surface 142 of plunger 130 is angled as is evidentparticularly in Figs. 7 and 8. This makes possible exertion of a cammingaction which can be'used to actuate the gun trigger. Accordingly thereis provided a cam 144 having a slope corresponding to that of surface142 of the plunger. A roller 146 rotatably mounted on a bail 148, orother suitable means, is interposed be.-

tween plunger surface 142 and cam 144. As a result,

when the plunger is depressed, the thrust is conveyed ment oflubrication, from the position of Fig. 7 to the position of Fig. 8. If aforeign substance, such as mud or snow, is introduced, the rollerremoves the obstruction in one stroke without roughening any of thesurfaces, as might be the case with a metal-to-metal sliding cam. Thebail does not function as a hub for the roller, but; merely to looselyretain it in approximately correct position, from which it might bethrust by dirt or vibration. Movement of the plunger and cam isfacilitated by antifriction means comprising a roller 150 rotatablyattached by means of bail 152 to plunger 130. This roller is mounted ina recessed portion of the side wall of the plunger whichis opposite thecam surface. Hence as the plunger is depressed, the side thrust of theoperation is exerted against roller 150 which moves to the position ofFig. 8. This makes possible smooth operation of the plunger; eliminatessticking; and eliminates the necessity of lubrication.

. The motion of cam 144 is translated into the angular motion of avertically mounted lever 154 (Fig. 5). The upper end of this lever isconnected through collar 158 to a shaft 156 which is journaled inopposite end walls of hollow cross is connected through collar 160 to avertically arranged lever 162. The lower end of this lever in turn isconnected through clevis member 164 to a tubular link member 166 whichextends substantially the length of the gun body and is mounted forlongitudinal movement. Means are provided for interconnecting tubularlink 166 with trigger 25 of the gun. Such means include means forcompensating for slight variations in trigger dilferent guns which maybe integrated with the assembly. This construction is illustrated inFigs. 12-14.

As is apparent from these views, link 166 extends into a longitudinalrecess 172 centrally located in a slide member 174. The latter member isinthe form of a T, the cross bar 176 of which is in sliding engagementwith a side wall of casing 30.

The other segment 178 of the Tshaped slide extendsmto the interior ofthecasing.

Its terminal portion is piece 82. The inner end of shaft 156 aermoaformed with a jaw 180 which releasably receives the end of trigger 25.Accordingly, when link 166 is moved to the leftas viewed in Fig. 12, itmoves the trigger to firing position. However, when pressure is releasedon button 110, the trigger spring of the gun forces the link, and thebutton, back to their normal positions.

A means which may be employed for adjusting the connection between slide174 and link 166 is illustrated in Fig. 14. To achieve the desiredadjustment, a screw 182 is threaded into the end of the recess 172opposite the end of link 166. The head of the screw is aligned with anopening 184 in casing 30. This makes possible turning the screw with ascrew driver until it just engages the end of the link, thereby insuringthat depression of button 110 will instantaneously move the trigger andfire the gun.

An alternate construction for the trigger actuating means is illustratedin Fig. 18. In this construction a hand grip 190 corresponding infunction to hand grip 80 of the previously described embodiment ismounted on the forward portion of casing 30. A housing 192 is rigidlymounted on the outer vertical face of the grip. A button 194 providedwith a locking wing 196 is mounted for vertical reciprocation in thehousing in a manner analogous to that in which button 110 is mounted inhousing 86. The movement of button 194 is limited by pin 198.

A flexible cable 200 is connected to the lower portion of button 194. Itpasses through a first tube 202 which is of substantial construction andpart of the hand grip. It then passes through a flexible tube 204rearwardly where it is connected to the trigger in the manner describedabove in connection with slide 174. Accordingly, depression of button194 trips the trigger, but against the force exerted by the triggerspring. Then when pressure is released on the button, the trigger springreturns it to its elevated position.

Operation The operation of the herein described forearm gun is as.follows:

First, forearm plate 52 is mounted on the forearm by means of strap 58and snap fastener 60. Then upper arm plates 62, 66 are put in place andfastened by means of straps 72, 74 and fasteners 76, 78. The position ofthese three plates relative to the arm is such that pin 64 whichinterconnects plates 52, 62 is in direct alignment with the elbow joint.As a result, the forearm may be moved in normal manner without bindingor restriction.

Next, belt 98 is placed about the waist with plates 100 and 102 towardthe front.

To mount the gun on the forearm, it is grasped in the left hand andswung out over the right forearm and the fingers of the right handslipped through grip 80 between strap 97 and connector 88. This placesthe right thumb in a natural position adjacent or above trigger button110.

Next, hook 36 on the rear portion of the gun casing is slipped over theupper edge of plate 52 whereupon dogs 38, 40 on the underside of thehook engage the adjacent serrations 54. on the upper edge of the plate.In this manner adjustment is made automatically for variations due touse of gloves or heavy clothing, or for individual variation of forearmlength. After the dogs 38, 40 engage serrations 54, the gun is releasedby the left hand and its weight causes latch portion 46 of clip 42 toclose over the lower edge of plate 52, thus locking the gun securely tothe arm.

The gun is now in the position of Fig. 1. It may be fired by pointingfrom the hip, or sight-aimed in the manner indicated in Fig. 3.

Before shooting, the safety catch comprising wing 112 on button 110. ismoved from the position of Fig. 7 to that of Fig. 8. This movement isaccompanied by a 90 shift in the position of balls124, 126 (Fig. 9) fromthe.

indicated position to that in which they occupy the other corners formedby the side walls of housing 86. This makes positive the adjustment ofthe safety between on and off positions. 1

Button 110, may be depressed when the safety is in its.

oif position. This in turri depresses plungerto theposition of Fig. 8,the lower limit of depression being determined, by the engagement ofspring pressed stop 136 with the bottom edge of slot 141. As plunger 130moves downwardly it moves cam 144 to the right as viewed in Figs. 7 and8, the interposed roller 146 facilitating this motion. Also, the actionof roller 150 interposed between the side walls of plunger 130 andhousing 86 takes the side thrust exerted by this motion so that themovement of the plunger is free and substantially frictionless, evenwithout. thebenefit of lubrication. The sideways movement of cam 144induces angular movement in lever 154 to which the cam is connected.This in turn moves lever arm 162 in cming 30 (Fig. 5) in the samedirection. As a result, link 166 is moved to the left as viewed in Fig.12. This causes slide 174 to move, to the left and accordingly actuatcstrigger 25 against the force exerted by the trigger spring of the gun.This fires the gun, after which the trigger spring forces link 166 andbutton 110 back to their former positions.

When the gun is fired, recoil is. transmitted painlessly to the arm bythe articulated and padded arm plates. These are so shaped as to bridgeall major blood vessels and nerves and to impose the weightsubstantially on the skeleton of the wearer, rather than upon flesh andmuscles. As a result the weapon can be carried on the arm for longperiods with little fatigue or discomfort, permitting free use of bothhands for practically any task, yet ready for instantaneous firingshould need arise. In addition, desirable effects noted fromexperimental firing include remarkable freedom from fiinching whileusing the thumb trigger, as complred to the finger trigger of aconventional gun; and a feeling of great comfort and stability inaiming, either from the hip or by means of the sights, due to the factthat the major part of the weight of the gun and ammunition is supportednear the elbow, rather than extending beyond the end of the hand, aswith a conventional pistol.

Where the need for use. of the gun is not likely to be acute, it may bemounted at the waist in the manner indicated in Fig. 2. In thisposition, belt hook 106 is inserted in the perforation in bracket 34 onthe gun casing. Hook 36 on the latter then is slipped over the serratedportion of plate 102 whereupon dogs 38, 40 are instantaneously receivedin the adjacent ones of serrations 104. Clip 42 then may be snappedunder the lower edge of the plate to anchor the gun on the belt.

If need should arise to shoot the gun while it is being worn at thewaist, this may be done without the necessity of removing it from thebelt. Thus the body may be turned to aim the gun and button 110depressed with the thumb of the left hand. Also, if desired ornecessary, the gun may be fired while being held in the hand, somewhatin the fashion of shooting a conventional rifle, except that triggeringis, performed with the left thumb.
